Guessing it is the motherboard at this point...
The topic is to see if anyone has any other helpful suggestions regarding what it could be, but I have had a myriad of issues with this computer for a little bit of time now. The computer monitor shows "No signal", and then goes black. This was normally fixed by removing both sticks of ram and then placing one inside the MB, and starting it back up. Once the ram was read at the correct voltage, I could then place the other stick of RAM in and have success for weeks to a month at a time. I did, however, install new video drivers for my GPU and now the monitor will not display anything at all.
GPU - Ati 5850
MB - Gigabyte EP43
Ram - G-skill 8500 DDR2
OS - Vista
HDD - Seagate 7200 rpm
I am very close to scrapping this P.O.S and keeping the vid card and the HDD and doing a whole new build.
